ABSTRACT:
In a device for noise configuration in a motor vehicle which has an internal combustion engine with at least two gas conduits connected to different cylinders of the engine, the gas conduits are interconnected by means of a cross-flow section formed by a housing which encloses the gas conduits and which has at least two chambers in each of which one of the gas conduits is disposed, each of the gas conduits being in communication with the respective chamber by which it is enclosed by means of a respective cross-flow opening and the two chambers being in communication with one another by means of at least one cross-flow opening which is remote from the cross-flow openings of the gas conduits so as to provide for a phase shift of the sound waves of the gas flowing through the housing.
